You can't remove the standard text, but you can insert text:

window.onbeforeunload = function (evt)
{
 var message = '!! Leaving this page may cause loss of data !!\n';
 
      if (typeof evt == 'undefined') 
    evt = window.event;

       if (evt)
           evt.returnValue = message;
 
   return message; 
 }

Welcome to Bytes. Your question has already been answered. You can add your own message but you can't remove the default message.
